Doucas Pigmented Purpura

Doucas Pigmented Purpura, also known as Schamberg’s Disease or Capillaritis, is a rare skin condition that leads to red, brown, or purplish discoloration on the skin. This article aims to provide a comprehensive yet easy-to-understand guide on Doucas Pigmented Purpura, including its types, causes, symptoms, diagnostic tests, treatments, and commonly prescribed medications.

Types of Doucas Pigmented Purpura

1. Progressive Pigmentary Dermatosis: This is the most common form of Doucas Pigmented Purpura and typically affects the lower legs. It leads to red or brown spots that gradually darken over time.
2. Purpura Annularis Telangiectodes: In this type, circular patches of purpura (purple or brown spots) with dilated blood vessels occur, often on the lower extremities.
3. Lichenoid Doucas Pigmented Purpura: This type presents as lichenification (thickened and rough skin) along with pigmentation. It can be itchy and often affects the lower limbs.
4. Actinic Purpura: Sun exposure is a major factor in this type of Doucas Pigmented Purpura. It results in easy bruising and purpura on sun-exposed areas of the skin.
5. Atrophie Blanche: This subtype involves white or pale spots within the purpuric areas. It’s more commonly seen on the legs and is associated with changes in skin texture.

Causes of Doucas Pigmented Purpura

1. Capillary Leakage: Small blood vessels, called capillaries, become leaky, causing blood to accumulate in the skin and leading to purpura.

10. Sun Exposure: Prolonged exposure to the sun’s ultraviolet (UV) rays can trigger or worsen Doucas Pigmented Purpura in some individuals.
11. Hormonal Changes: Hormonal changes during pregnancy or menopause may influence the development of this condition.
12. Medications: Some medications, such as aspirin, can increase the risk of Doucas Pigmented Purpura.
13. Infections: Bacterial or fungal infections can occasionally be associated with this skin disorder.
14. Chronic Venous Insufficiency: Poor circulation in the legs can contribute to the development of Doucas Pigmented Purpura.

2. Itching or Burning Sensation: Some individuals may experience itching or a burning sensation in the affected areas.
3. Circular Patches: In some cases, the purpura forms circular patches with a clear center.
4. Thickened Skin: Lichenoid Doucas Pigmented Purpura can lead to thickened and rough skin.
5. White Spots: Atrophie Blanche subtype is characterized by white or pale spots within the purpuric areas.
6. Easy Bruising: Actinic Purpura may cause the skin to bruise easily, especially after minor trauma.
7. Leg Swelling: Chronic venous insufficiency associated with Doucas Pigmented Purpura can lead to leg swelling.

Diagnostic Tests for Doucas Pigmented Purpura

1. Clinical Examination: A dermatologist will examine the affected skin to make a preliminary diagnosis.

6. Skin Allergy Tests: These tests can determine if specific allergens are contributing to the condition.
7. Phototesting: For Actinic Purpura, phototesting involves exposing the skin to UV light to see how it reacts.
8. Venous Doppler Ultrasound: This test may be performed if there are concerns about venous insufficiency.
9. Skin Scraping: In cases where fungal infection is suspected, skin scrapings may be examined under a microscope.
10. Ruling Out Other Conditions: Sometimes, tests are done to rule out other skin conditions that may mimic Doucas Pigmented Purpura.

Treatments for Doucas Pigmented Purpura

1. Observation: In mild cases, no treatment may be necessary, and the condition is simply monitored.
